Built using advanced Object-Oriented Geospatial Component model, H₂OMAP Water provides the most powerful and practical GIS platform for water utility solutions. As a stand-alone GIS-based program, H₂OMAP Water combines spatial analysis tools and mapping functions with sophisticated and accurate network modeling for complete infrastructure (asset) management and business planning. It performs fast, reliable and comprehensive hydraulic and dynamic water quality modeling, energy management (with true variable speed pumping), real-time simulation and control with on-line SCADA interface, complete fire flow analysis, and unidirectional flushing. The program can also be effectively used to analyze pressurized sewer collection system.

H₂OMAP Water fully supports geocoding and multiple mapping layers which can be imported from one of many data sources including Computer-Aided Design (CAD) drawings (e.g., dwg, dgn, dxf), CAD world files, standard GIS formats (Shapefiles, Generate files, MID/MIF files, and ArcInfo coverages), Vector product format (vpf) files, Spatial Database Engine (ArcSDE) Layers, attribute tables, grid data, image files, ODBC, and Comma Separated/Delimited Text (CSV) files. The program also supports the new geodatabase standard of ArcGIS through an ArcSDE connection.

H₂OMAP Water MSX (Multi-Species eXtension) adds very powerful modeling capabilities including the unprecedented ability to accurately model multiple interacting contaminants as well as sediment deposition and re-suspension in drinking water distribution systems. H₂OMAP Water MSX allows users to model very complex reaction schemes between multiple chemical and biological species in the water distribution piping system, both in the bulk flow and at the pipe wall. This structure gives users the flexibility to accurately model multi-source, multi-quality systems and a wide range of important chemical reactions including free chlorine loss, formation of disinfection byproducts, nitrification dynamics, disinfectant residuals, pathogen inactivation, chloramine decomposition, and adsorption on pipe walls.

While there are a number of commercially available programs for modeling the hydraulic and water quality behavior of drinking water distribution systems, their water quality component is limited to a certain number of fixed kinetic models, and to tracking the transport and fate of a single chemical species, such as fluoride or free chlorine. H₂OMAP Water MSX can effectively model any system of multiple, interacting chemical species. In addition, the program allows users to input any mathematical models of physical, chemical, and biological reactions in the bulk water and on pipe surfaces. It also accepts any number of user-specified (adding water quality) parameters and formulas for process models.

H₂OMAP Water MSX can also be effectively used to track the movement, fate and build up of particulate material in the water distribution system. It considers both settling of particles under gravity as well as deposition of particles on the pipe walls due to particle/pipe surface attractive forces. This feature can greatly assist water utilities in improving distribution design to minimize dirty water and forge closer ties with their customers.
